Abstract (en)

[origin: EP0102059A2] A loop transmission system is disclosed which, on the failure of a transmission path in an active loop or transmission paths in both active and back up loops between adjacent transmission devices, automatically switches all the transmission devices from one of the loops to the other, without observing any particular transmission device, so that the whole system is capable of reconstructing a new loop. A faulty portion is located and a loop back configuration is set up excluding the faulty portion.
